Specs for a giant OCR 2
The Giant OCR 2 road bike is an entry-level bicycle for both commuters and recreational riders. The lightweight frame is considered an advantage of the OCR 2, although it also makes it slightly pricier than other entry-level bikes.
The Giant OCR 2 uses Giant's Compact Road Design and has a butted ALUXX aluminium frame with a carbon-composite fork, which helps to reduce the weight of the bicycle. The frame is built for riding comfortably for multiple hours at a time, although some reviews caution that it is not conducive for riding in the tucked position.
The handlebar and stem for the OCR 2 are made from 6061 aluminium alloy, and the bike features a Formula One Composite seat post. The bike has Shimano Tiagra shifters and front derailleur and a Shimano 105 rear derailleur. The cassette features a triple-ring, SRAM PG950 12-26 9-speed system. The middle ring is a size 39, which is constructed for providing a smooth cadence on flats and small ups and downs. Rims, hubs and spokes are all Xero XSR-4. Factory tires come in Kenda Kontenders 700x25.
The Giant OCR 2 as of November 2010 sells through online retailers in the £585 to £650 range. The bicycle comes in five sizes, ranging from extra small to extra large.
